Question

In a calibration test, 10 measurements using a digital voltmeter have been made of the voltage of a battery that is known to have a voltage of 6.11 V. The readings are: 5.98, 6.05, 6.10, 6.06, 5.99, 5.96, 6.02, 6.09, 6.03, and 5.99 V.
i) Explain how you would use the calibration test data to correct this digital voltmeter.
ii) State at least a merit and a demerit of the correction method you have discussed in part i).
